Hi guys, i'm in a dilemma here. I have 2 second hand exhaust system to choose from. First is a Ganador titanium wif 80mm piping and the other is a Trust TR Power Evolution wif 94mm piping. The difference is only AUD300 (Ganador being the more exp one). my current Nismo exhaust is 80mm but it has a big square restrictor kinda box.

Current mods are not extensive- apexi air filter, fcon vpro, boost controller, tomei fuel pump. Gonna keep the rest stock for next 1-2 years.

Which one should i choose? i'm just afraid the Trust one wud get me in some serious shit wif the cops.

Your opinion are much appreciated.

Get the Trust and spend the money you saved on a decent hiflow cat, if you haven't already. Else its a compromise between noise and flow.

What's your power target? That tells you what size exhaust you will need. My rule of thumb;

Up to 250 rwkw = 3"

250 rwkw to 300 rwkw = 3.25"

300 rwkw to 400 rwk = 3.5"

Over 400 rwkw = 4"

:P cheers :)

So say my target for now is 300 - 400 rwkw. If i change to to 4" piping, would it compromise my mid-range torque?

The intlet of the ganador muffler is relatively small (which is currently same size as my nismo which looks to me something like 2.5"!!) when compared to other mufflers in its class. This is the reason why i wanted to change my nismo exhaust. If i were to choose this ganador muffler, it wud be for its straight flow shape n its lightness (as opposed to the nismo's "s-shaped" piping n heaviness. My question is, is it worth it?

Thanks for your opinions again. very much appreciated.

Having too big an exhaust is NOT a problem on a turbo charged engine. As far as power goes anyway, although it might be a noise problem of course. Titanium tends to be noisier than stainless steel, it doesn't absorb the sound as much, the titanium seems to echo more.

We use titanium exhausts on the race cars for their light weight, a 4" titanium system is less than 1/4 the weight of a 4" stainless system. But they are expensive and very difficult to repair it they get damaged. Personally on a road car I would stick to steel.

:rofl: Cheers :D

My worry abt the 4" exhaust was the compromise in mid range torque. So since it wudnt be affected (apart fr the noise level) then i might as well get it then instead of the Ganador Titanium. Then at least when i'm ready for more power i dun haf to change my exhaust again.

Thanks!

    • To expand on this to help understanding... The bigger/longer the block is, the more it's going to work to sit on your far away high areas, and not touch the low stuff in the middle. When you throw the guide coat, and give it a quick go with a big block, guide coat will disappear in the high spots. If those high spots are in the correct position where the panel should be, stop sanding, and fill the low spots. However, using a small block, you "fall off" one of the high spots, and now your sanding the "side of the hill". Your little block would have been great for the stone chips, where you only use a very small amount of filler, so you're sanding and area let's say the size of a 5/10cent piece, with something that is 75*150. For the big panel, go bigger!   And now I'll go back to my "body work sucks, it takes too much patience, and I don't have it" PS, I thought your picture with coloured circles was an ultra sound... That's after my brain thought you were trying to make a dick and balls drawing...
    • Oh I probably didn't speak enough about the small sanding block for blocking large areas.  In the video about 3 minutes in, he talks about creating valleys in the panel. This is the issue with using a small sanding block for a large area, it's way too easy to create the valleys he is talking about. With a large block its much easier to create a nice flat surface.  Hard to explain but in practice you'll notice the difference straight away using the large block. 
    • Yep I guessed as much. You'll find life much easier with a large block something like this -  https://wholesalepaint.com.au/products/dura-block-long-hook-loop-sanding-block-100-eva-rubber-af4437 This is a good demo video of something like this in use -    You have turned your small rock chip holes into large low spots. You'll need to fill and block these low spots.  It's always a little hard not seeing it in person, but yes I would go ahead and lay filler over the whole area. Have a good look at the video I linked, it's a very good example of all the things you're doing. They went to bare metal, they are using guide coat, they are doing a skim coat with the filler and blocking it back. If what you're doing doesn't look like what they are doing, that's a big hint for you  
    • The odometer does go up when driving.  Does this tell it is an issue with the speedometer itself?    Where can I look for replacement cluster? Or speedo? I can likely do the repair.. Will ER34 cluster work on HR34? Or do I need a HR34 20GT S2 specifically lol   
    • Mine's a bit bigger at 70x150mm roughly. The spots are flat, just can feel the edges if I dig my nail into it. I did fix some other other ones by both using my finger to sand that small spot (I'm a bit wary of doing this and creating hot spots and a bigger mess) and I also did sand over it flat and others, but this also worried me a bit because if I create an overall low spot on the panel on paint that is good.  Correct me if I'm wrong but as long as it's flat even if I can feel the edges, I can put filler because it will all be level once I sand it? I can see myself going in a circle after sanding guidecoat with 320 grit if for example the panel is flat with my hand but because I sanded the guidecoat I could have created a low spot again somewhere. Unless where I'm going wrong is what I mentioned previously where I didn't go low enough on the grits. It's 1 step forward and 2 step backwards here haha. I'll probably need to experiment with it more. Last time I go back to bare metal lol.
